B. Aortic transplantation In the rat-inner aortic transplantation model, an allogeneic response to the graft will not destroy the graft, but it will trigger pathological variations similar to the symptoms of chronic rejection in clinical transplantation. These include the penetration of monocytes (lymphocytes, macrophages, and some plasma cells) into the adventitia of the arteries, and the thickening of the lining of the blood vessels. A male aorta with a length of about 1 cm between the branch of the renal artery and the start of the tail mesenteric aorta was obtained from a male DA (RT1a) rat and transplanted in the same position in a male Lewis (RT11). Inside the rat. The weight of the rats was recorded every week after the transplantation. During the dissection of the cadaver, the graft and the recipient's graft and the aorta just above and below it were removed. This part was completely immersed in vitro with a phosphate buffer solution containing 2% paraformaldehyde and 2.5% glutaraldehyde for about 2 minutes, and then immersed and fixed in Baitong solution for fixation. 24 12 This paper size applies to China Standard (CNS) A4 Specification (210 X 297 mm) -------- Order --------- Line (Please read the precautions on the back before filling this page) 550074 Intellectual Property of the Ministry of Economic Affairs A7 B7 printed by the Bureau ’s Consumer Cooperatives 1.

Description of the invention () After the balloon-like injury, 14 days (+14 days). Rats are placed in an independent iron cage and infinite Food and water were given. The rats were then anesthetized with isoflurane, a perfusion catheter was inserted through the left ventricle of the heart and the aortic arch was tightened, and then a suction cannula was inserted into the right ventricle of the heart. The animals were perfused at a pressure of 1 Perfused at 50mmHg, initially perfused with 0.1M phosphate buffer solution (PBS, ρ ， 7.4) for 1 minute, and then perfused with phosphate buffer solution (P 溶液 7.4) containing 2.5% glutaraldehyde solution for 15 minutes The perfusion pressure at the tip of the cannula is 150 mmHg (approximately equal to the intra-aortic perfusion pressure of 100 mmHg, which was determined in a preliminary experiment by inserting a cannula connected to a pressure transducer into the external cervical artery). The carotid artery tube was subsequently excised, separated from the surrounding tissue and immersed in 0.1 M dimethylarsenate buffer (ρΗ7.4) containing 7% sucrose and cultured overnight at 4T :. The next day, the carotid artery was placed in a 0.1 M dimethylarsenate buffer solution containing 0.05% potassium permanganate at room temperature, soaked and shaken. The tissue was subsequently dehydrated with a series of ethanol of different concentrations; twice in 75% ethanol for 10 minutes each; rain in 85% ethanol for 10 minutes each; three times in 95% ethanol For 10 minutes and three times in 100% ethanol for 10 minutes each time ... Follow the manufacturer's recommendation to embed the dehydrated carotid artery into the Technovit 7100. Since oxygen was found to inhibit the achievement of a suitable hardness, the embedding medium was placed in a desiccator under argon for polymerization overnight. Using a hard metal knife in a rotary microtome, 15 papers from each carotid artery are applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) -------- ^ ----- ---- (Please read the notes on the back before filling this page) 55〇07 4 Printed A7 B7 $ printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the middle section of the invention description () cut out 1-2 microns Thick cut surfaces and stained with golden sand's dye for 2 minutes. Approximately 5 sections were prepared in this way from each carotid artery, and the media, neovascular intima, and cross-sectional area of the lumen were assessed by a morphological bridge system (MCID, Steal More, Canada). In this test, when the daily oral dose of each animal is 0.5 to 2.5 mg of the compound of formula I per kilogram of body weight, the myointimal proliferation is inhibited. The thickening of the vascular intima in the blood vessels of rats receiving Compound A was significantly less than that in the control group. For example, in the animals receiving 0.5 mg per kilogram of body weight, 50% of the neovascular intima was formed. Inhibition effect was observed in 75% of animals receiving 2.5 mg per kg body weight. D. Living Heart Xenotransplantation (Mole Voles to Rats) The combination of xenograft transplanting Voles to rats is a so-called difficult combination. There is no natural anti-vole antibody in rats, and this kind of antibody can produce direct hyperacute rejection in sufficient amount, as observed in the consistent group; however, rejection within 3-4 days Action rejection occurs in untreated recipients, which is produced by antibodies and complement. These reactions are manifested in the destruction of blood vessels in the tissues, the exudation and extravasation of red ¢ 1 spheres, and the influx of granulocytes from polymorphonuclear leukocytes; usually those are signs of bleeding and thrombosis. Once such rejection has been achieved by effectively inhibiting the formation of antibodies or inactivation of complement 16 ^ paper size applies Chinese National Standard (CNS) A4 specifications (210 X 297 mm) ------------ -------- Order --------- line (please read the notes on the back before filling this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 550074 A7 __ B7 V. Description of the invention () To overcome, then a cellular rejection can be seen. These reactions are manifested in tissues by the influx of monocytes, including lymphoblasts, lymphoblasts, and macrophages, and the destruction of substantial portions of muscle cells. For cell killing, it requires more immunosuppression. Rats with congenital thymus deficiency (mii / mu) lack an intact cellular immune system (thymus-dependent) and usually cannot reject allografts. This animal can reject voles xenografts in 3-4 days, similar to the response in normal thymus rats, showing that (at least part of) the synthesis of anti-voles antibodies in rats is Produced by a thymus-dependent B-cell response. Such recipients can help evaluate rejection by thymus-independent antibody-mediated rejection during vole xenograft surgery. A Syrian voles heart was ectopically transplanted into the abdomen of a male Lewis (RTl ') rat and the aorta of the donor and the recipient was connected, and the donor's right pulmonary artery was connected to the recipient's lower Intravenous cavity. The graft is observed daily by palpation of the abdomen. Rejection ends when the animal's heartbeat stops. Animals are weighed every week. In this series of experiments, termination was set at day 28. The animals were killed and dissected; the grafts were removed and their weights and tissues were examined on the thymus, spleen, liver, small intestine and testes. The blood of the animal was taken out and processed into blood iW *, and the cytolytic anti-vole red blood cell antibody and hemolytic complement activity were measured. In this kind of test, the compound of formula I (compound A), when the paper size is exemplified, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied. -------- Order ----- ---- Line (Please read the precautions on the back before filling this page) 550074 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V.
